Stainless steels are high-alloy steels that have excellent corrosion resistance in comparison with other steels as they contain more chromium. Based on their crystalline structure, stainless steels are divided into three groups, namely, martensitic, austenitic and ferritic steels. A combination of martensitic and ferritic steels forms a fourth group known as precipitation-hardened steels.
